freemax mesh pro is pretty widely considered the best Sub ohm tank out their atm , Its not for MTL though , but im guessing thats not what your after anyhow , And it drinks juice... But i have two of them and i love them , That said i would go with the double mesh , the single just isnt as good , and the triple upwards whilst providing better flavour you have to run them high wattage and they drink more.
